Introduction: The study examines the impact of intra-articular hyaluronic acid injections on arthrogenic contractures in rat knee joints, focusing on the remobilization phase after immobilization-induced contractures. Methods: Utilizing a controlled experimental design, the study involved rats with induced knee joint immobilization, followed by treatment with intra-articular injections of hyaluronic acid. Measurements of range of motion (ROM) were used to assess the effectiveness of the treatment. Results: The treatment group showed a significant improvement in knee joint ROM compared to controls, indicating that hyaluronic acid injections effectively reduce contractures and improve mobility. Discussion: The findings support the therapeutic potential of hyaluronic acid in treating joint contractures, suggesting a beneficial approach for post-immobilization recovery in clinical settings.
